Specification of Letters Patent.

Patented July 27, 1915.

Application filed May 23, 1914. Serial No. 840,547;

To all whom t may concern:

Be it known that we, RICHARD B. Fnrnsn and Luo LA POINTE, citizens of the United States, and residents of the city of Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Impro\ ements in Etchers Cleaning-Tables; and we do hereby declare'that the following is a full, clear, and eXact description of the same, reference being had to the accompanying drawings, and to the numerals of reference marked thereon', which form a part of this specification.

The cleaning off operation in an etching or engraving process has always been more or less disagreeable, as well as inconvenient. Furthermore, the turpentine, after use in cleaning the etched plates of remaining traces of the ground and particles of smut, is generally poured into a container for future use, but after a time it becomes dirty and must be dispensed with.

It is the purpose of the present invention to construct a device upon'which an etched plate may be cleaned, the turpentine used in the process flowing into a clarifying or separating means from which it may be drained from time to time, free from inpurities and capable of being usedfor a considerable time in a number of subsequent operations.

It is an object of this invention to construct a cleaning table upon which an etched plate may be conveniently supported and washed with turpentine, the turpentine flowing into a separating or clarifying means which is associated with the device in a manner permitting ready removal thereof for cleaning or repair.

It is also an object of this invention to construct a device wherein a plurality of interfitting separating containers are releasably associated with one another and pivotally mounted beneath a supporting table to receive a washing fluid drained from the dtable for the purpose of clarifying the iiui It is also an object of this invention to construct a supporting table embracing a coarse wire screen support upon which the object is placed to be washed, the washing fluid draining into a clarifying means, said screen and said clarifying means being detachable from the device for the purposes of repair or cleaning.

It is furthermore an object of this invention to construct a simple device adapted to collect the washing iud used in cleaning etched plates and to clarify the same, Said device being provided with suitable valve connections by which the clarlied fluid may be drained away in amounts desired for subsequent use.

It is finally an object of this invention to construct a device consisting of few parts, conveniently associated with one another for ready detachment for the purposes of repair or cleaning thereof,

The invention (in a preferred form) is illustrated in the drawings and hereinafter more fully described.

In the drawings: Figure 1 is a front view partly in section of a device embodying the principles of our invention. Fig. 2 is a top plan View thereof with parts broken away. Fig. 3 is a fragmentary section taken on line 3-3 of Fig.V 1. Fig. l is a section taken on line lr-4 of Fig. 3. Fig. 5 is a fragmentary detail section taken on line 5-5 of Fig. 2.

As shown in the drawings: the device comprises a rectangular frame, composed of three Vvertically disposed Walls 1, 2, and 3, which are of substantially the same depth and a fourthwall hwhich, as clearlyshown in Fig. 1, is approximately one half the depth of the others so that said frame is open on one side, permitting ready insertion or removal of an article. Said frame is supported by four legs 5, each one of which is conveniently disposed beneath the frame at one of the four corners thereof. An inner peripheral partition 6, vextends around and is secured upon the surface of the walls of the frame and is chamfered of:1 on its edge so that a .large spout 7, having a horizontal flange or lip 8, may be readily secured and supported upon saidqpartition. As clearly shown in Fig. 5, the four walls of said spout converge downwardly in the form of a frustum of an inverted pyramid. A band 9, is attached around the outer'surface of said spout member near the lower end thereof, and connected on one side thereof by means of a hinge 10, is an apertured block 11, pro-vided with a pin 12, adapted to engage upwardly through a slot in said band to be releasably held rtherein by a slidingbar 13. A conical outer container 14, is anged over at its upper end and extends through and is supported in said block 11. At its lower end said container is provided with an eX- teriorly threaded collar 15, on which is secured an enlarged apertured cap 16, which acts-'Ahold'a fine meshvscreen 17, in posip supported'a downwardly facing protecting shield 20. A strong Vsupporting screen 21,

' secured on two of its edges to angle irons 22,

is of a size permitting the same to iit closely within the frame formed by the walls 1, 2, and 3, of the device, resting upon the flanged portion 8, of the spout member, and is'capable of being slidably removed from the frame on they open side thereof over the small frame wall 1. Supported coaXially Within said outer container 141, is an inner container 23,' the upper open end thereof eX- tending above and around the lower end of the spout 7, and anged over, as indicated by the reference numeral 24, to rest upon the iianged lip of the outer container 14. Said inner container 23, as clearly shown in Fig. 3, is closed at its lower end, but a plurality of apertures 25, are disposed peripherally in Vthe walls thereof ashort distance below the 'upper end'thereof.

The operation is as follows: IVhen an etched or engraved plate is to be washedit is placed. upon the screenrsupport 21, and the turpentine or other fluid is applied. The iiuidl drains down through the spout 7, and into the inner container 23, the particles of sediment or other impurities washed from therplate thereupon settling to the bottom 'of saidinner container, but the clear liquid at the surface iiowing outwardly through the apertures 25, 'into the outer container 14, said containers thus forming a sediment trap. 'Ihe Huid may be withdrawn from said outer container in suitable quantities as desired by opening the cock 19, and of course the fine wire mesh screen 17, in the bottom of Copiesof this patent may be obtained for saidouter container serves to eifectually clear the outflowing liquid of'any traces of remaining impurities. When it is desired to clean or repair the device, the screen 21', may be easily removed and washed, and by retracting the slide bar 13, the associated inner and outer containers swing downwardly upon the hinge 10. The inner container 23, may then be lifted out and the collected impurities at the bottom thereof removed, and the container washed and thoroughly cleaned. For the purpose of cleaning the screen 17, at the bottom of the outer container either the cap 16, may be removed or the container may be lifted out of the supporting block 11, and cleaned without detachment of the screen.

We are aware that various details of construction may be varied through a wide range without departing from the principles of this invention, and we therefore do Vnot purpose limiting the patent granted otherwise thanV necessitated by the prior art.

We claim as our invention:

1. In a device of the class described, a rectangular frame, an inner peripheral partition therein ehamfered at its inner edge, a spout overlapping said partition and depending therefrom, a removable screen adapted to be slid edgewise into position upon said peripheral partition, and a sediment trap located beneath the spout and into which the latter discharges.

2. In a device of the class described, a supporting table for the articles to be washed, a spout to receive the drain washing fluid depending from said table, an apertured block supported from the lower end of said spout and of larger diameter than its discharge end, a sediment trap hinged at one side to said apertured block, and means for retaining said trap at its other side detachably in engagement with said block.

In testimony whereof we have hereunto subscribed our names 1n the presence of two subscribing witnesses.
